The correct answer is

3

To solve the problem, we need to identify the vowels in the given letter series that are immediately preceded and followed by consonants.

Step-by-step solution:

  1. First, identify all the vowels in the series: A, E, O, A, U.
  2. Now, we need to check each vowel to see if it is preceded and followed by consonants:
    • A: Preceded by (None) and followed by T
    • E: Preceded by D and followed by B - This satisfies the condition.
    • O: Preceded by Q and followed by N - This satisfies the condition.
    • A: Preceded by E (This does not satisfy the condition as E is a vowel) and followed by O
    • U: Preceded by F and followed by K - This satisfies the condition.
  3. Counting all vowels that meet the criterion: E, O, and U.

Therefore, the number of vowels each of which is immediately preceded and followed by a consonant is 3.

Hence, the correct answer is 3.

To solve these types of questions effectively:

  • Quickly identify the vowels and target their positions in context.
  • Carefully check the preceding and following letters to confirm they are consonants.
